White Blood Cells
By Barbara Liang
In this animated and interactive object, learners examine the structure and functions of granulocytes and agranulocytes. Two exercises complete the activity.
What Is Torque? (Screencast)
By Terry Bartelt
Learners read a description of torque and study the factors that cause its magnitude to change.
What Is Electricity?
The learner studies how electrons travel from one atom to the next. Examples demonstrate how voltage is created by the use of a battery or through magnetism. A quiz completes the activity.
Viruses
By Jonathan Harris
In this animated learning object, students examine the life cycles of a virus.
Virus Particles: Structure and Function
By Kristine Snow
In this learning activity you'll assembles parts of a virus and match virus terms and descriptions.
Virus Matching Exercises
Learners complete two exercises. In the first quiz, they divide viruses into two categories: RNA and DNA. They later match each virus with the disease it causes.
Vapor Pressure
By Debbie McClinton, Dr. Miriam Douglass, Dr. Martin McClinton
Vapor pressure is the pressure exerted by molecules in the gas phase in equilibrium with a liquid or a solid. Two examples are used to illustrate vapor pressure: the drying of clothes and the evaporation of ice.
Using Graphs to Explain Motion (Screencast)
By Henry Merrill
In this screencast, you'll observe two vehicles moving across the screen at different rates then describe the motion. Additionally, you'll select the corresponding graphs of distance vs. time, velocity vs. time, and acceleration vs. time for each vehicle.
Unit Conversions
By Jill Larson
In this animated and interactive object, learners follow two rules to write unit conversion fractions.
Types of Elements in the Periodic Table and Their Properties (Screencast)
By Debbie McClinton, Dr. Martin McClinton
In this screencast, we review the positions of metals, metalloids, and nonmetals in the Periodic Table and the general characteristics of each.
Transport Processes Requiring ATP
In this animated object, students observe how ATP energy is used to move substances across the cell membrane from an area of lower concentration to an area of higher concentration and when something too large needs to get in or out of a cell.
Tissue Identification
In this learning activity you'll review the structure and function of the different tissues of the human body.
Thermodynamic Transfer
In this animated object, learners examine how thermal energy is transferred by conduction, convection, and radiation. A brief quiz completes the activity.
The Zygomycetes (Screencast)
In this screencast, learners examine the lifecycle of fungi including asexual and sexual reproduction. Learners test their knowledge by identifying a diagram. There is a companion crossword puzzle game here: https://www.wisc-online.com/arcade/games/natural-science/science-biology/3016/the-zygomycetes-crossword
The Vertebral Column
Learners read a brief description of the vertebral column and examine the distinctive features of the cervical, thoracic, and lumbar vertebrae.
The Vascular System of the Kidneys
By Becky Polk-Pohlman
Learners play a vascular system "game" to identify the arteries, capillaries, and veins that make up the renal blood supply pathway. A score is given at the end of the activity.
The Upper and Lower Motor Neurons (Screencast)
In this screencast, learners examine the function and location of the motor neurons and the damage that can result when they are injured.
The Unipolar and Multipolar Neurons
Learners examine the location, structure, and function of the unipolar and multipolar neurons.
The Two-Neuron Knee-Jerk Reflex Arc
In this interactive object, learners examine the neuron pathway into and out of the spinal cord. They complete the activity by testing their knowledge of vocabulary and the location of spinal cord structures.
The Three States of Matter
By Dr. Miriam Douglass, Dr. Martin McClinton
In this animated and interactive object, learners examine the properties of liquids, solids, and gases.
The Structure of the Muscle Organ
In this animated object, learners examine the various connective tissue layers of the muscle organ. The terms "prime mover," "synergist," "antagonist," "origin," and "insertion" are defined.
The Structure of an Atom
Students examine atomic structure and the octet rule.
The Stress Response
In this animated object, learners read a brief description of the roles of the hypothalamus, emotions, and adrenal secretions during the stress response.
The Solid State
In this well-illustrated object, learners examine the structures and properties of the four types of solids: molecular, metallic, ionic, and covalent network. Five interactive questions are provided.
The Sense of Taste
In this interactive object, learners examine the structure and function of the sense of taste.
